摘　　要：三肇凹陷东部姚家组一段葡萄花油层为本区主要储层和含油层位,也是区内目前增储上产的重要目的层。储层的分布与物源有密切的联系,物源体系分析是油气勘探的一项重要工作。本文通过岩心观察描述以及分析化验资料的综合研究,从重矿物组合、ZTR指数变化特征、泥岩颜色区域分布以及砂体展布特征等方面对物源方向进行了分析,确定了三肇凹陷东部姚家组一段葡萄花油层物源体系,并对每个物源的影响范围和强度变化进行了综合分析和厘定,为下一步沉积体系的精细研究和储层预测奠定了基础。The Putaohua reservoir in 1st Member of Yaojia Formation within Sanzhao depression is the main reservoir,oil layer and also the important target reservoir for increasing production in the study area.The distribution of the reservoir has intimate relationship with the source,and hence the source system analysis is an important task in petroleum exploration.Based on core observation and description as well as a comprehensive study of the analytical data,the authors analyzed the source direction in terms of heavy mineral assemblage,ZTR index variation characteristics,regional distribution of mudstone color and features of sand distribution.The source system for Putaohua reservoir in 1st Member of Yaojia Formation within Sanzhao depression was determined,and the affected area and intensity variations of each source were comprehensively analyzed and determined.The results have laid a good foundation for precise study of the sedimentary system and prediction of the reservoir.
